-# Emoji Substitution
-
-**This add-on injects JavaScript into web pages. The `addons.mozilla.org` domain disallows this operation, so this add-on will not work properly when it's run on pages in the `addons.mozilla.org` domain.**
-
-## What it does
-
-Replaces words that describe an emoji with the emoji itself. This runs as a content script and scans web pages, looking for text that can be replaced with emoji. As an example, after installing visit https://mozilla.org and notice that the text "firefox" should change.
-
-## What it shows
-
-A good example for beginners that can be used as a "make your first add-on" tutorial and / or referenced to create other add-ons.

-## What it shows
-
-This shows how to configure a WebExtension with
-[eslint](http://eslint.org/)
-to protect against
-writing JavaScript code that may be incompatible with modern versions of
-Firefox or Chrome.
-
-## How to use it
-
-This requires [NodeJS](https://nodejs.org/en/) and [npm](http://npmjs.com/).
-
-* Change into the example directory and run `npm install` to install all
-  dependencies.
-* Execute `npm run lint` to view a report of any coding errors.

-## What it does
-
-This extension allows you to search the Firefox codebase using the awesome bar.
-
-To test it out, type 'cs' into the awesome bar followed by a search string (e.g. `cs hello world`). The results will be shown as suggestions, and clicking on a suggestion will navigate to the file where the result was found.
-
-To search a specific file, use the "path:" prefix (e.g. `cs hello path:omnibox.js`)
-
-## What it shows
-
-How to use the omnibox API to add custom suggestions to the awesome bar.

-#Mocha client tests for WebExtensions
-##Introduction
-This example shows two methods of testing a WebExtension:
-* Running tests from within the addon
-* Running tests from the commandline using Karma
-
-See https://github.com/Standard8/example-webextension for a more complete example of WebExtension test configuration.
-
-##Install Dependencies:
-```
-  npm install
-```
-To run tests from within the addon:
-```
-  cd addon
-  npm install
-```
-
-##Testing within the Addon
-This gives you the possibility to run client tests inside the addon with the mocha UI.
-If you don't want to use the mocha UI, you can install [WebConsole-reporter](https://github.com/eeroan/WebConsole-reporter).
-
-###Run with web-ext cli
-Just run `npm run web-ext` (will work with FF dev edition), if you have error with web-ext cli please add path for FF binary file with `--firefox-binary /path/to/firefox-bin`
-[(web-ext docs)](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/web-ext_command_reference).
-
-When the addon starts, click on the mocha icon in your browser bar to run the tests:
-
-![addon screenshot](screenshots/addon-button.png "Mocha test addon")
-
-This will test  `./addon/background.js` with `./addon/tests/lib/background-messaging.test.js`.
-
-##Testing from the Commandline
-This uses [Karma](http://karma-runner.github.io) to run tests from the commandline. Just type `npm test` to test `./addon/background.js` with `./tests/lib/background.test.js`.
-
-###Debug  Mode
-Use `npm run test:debug` to run Karma in watch mode. Whenever you modify a Javascript file, the tests will automatically rerun.
-
-You can install [karma-notification-reporter](https://www.npmjs.com/package/karma-notification-reporter) to display test results in a desktop notification. You'll need to add `--reporters=dots,notification` to the `test:debug` command line of
-`package.json` to enable it.

-This is a very simple example of how to use [native messaging](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Native_messaging) to exchange messages between a WebExtension and a native application.
-
-The WebExtension, which can be found under "add-on", connects to the native application and listens to messages from it. It then sends a message to the native application when the user clicks on the WebExtension's browser action. The message payload is just "ping".
-
-The native application, which can be found under "app", listens for messages from the WebExtension. When it receives a message, the native application sends a response message whose payload is just "pong". The native application is written in Python.
-
-## Setup ##
-
-To get this working, there's a little setup to do.
-
-### Mac OS/Linux setup ###
-
-1. Check that the [file permissions](https://en.wikipedia.org/wiki/File_system_permissions) for "ping_pong.py" include the `execute` permission.
-2. Edit the "path" property of "ping_pong.json" to point to the location of "ping_pong.py" on your computer.
-3. copy "ping_pong.json" to the correct location on your computer. See [App manifest location ](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Native_messaging#App_manifest_location) to find the correct location for your OS.
-
-### Windows setup ###
-
-1. Check you have Python installed, and that your system's PATH environment variable includes the path to Python.  See [Using Python on Windows](https://docs.python.org/2/using/windows.html). You'll need to restart the web browser after making this change, or the browser won't pick up the new environment variable.
-2. Edit the "path" property of "ping_pong.json" to point to the location of "ping_pong_win.bat" on your computer. Note that you'll need to escape the Windows directory separator, like this: `"path": "C:\\Users\\MDN\\native-messaging\\app\\ping_pong_win.bat"`.
-3. Edit "ping_pong_win.bat" to refer to the location of "ping_pong.py" on your computer.
-4. Add a registry key containing the path to "ping_pong.json" on your computer. See [App manifest location ](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Native_messaging#App_manifest_location) to find details of the registry key to add.
-
-## Testing the example ##
-
-Then just install the add-on as usual, by visiting about:debugging, clicking "Load Temporary Add-on", and selecting the add-on's "manifest.json".
-
-You should see a new browser action icon in the toolbar. Open the console ("Tools/Web Developer/Browser Console" in Firefox), and click the browser action icon. You should see output like this in the console:
-
-    Sending: ping
-    Received: pong
-    
-If you don't see this output, see the [Troubleshooting guide](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Native_messaging#Troubleshooting) for ideas.

-# navigation-stats
-
-## What it does ##
-
-The extension includes:
-
-* a background which collects navigation stats using the webNavigation API,
-  and store the stats using the storage API.
-* a browser action with a popup including HTML, CSS, and JS, which renders
-  the stats stored by the background page
-
-
-When the user navigate on a website from any of the browser tabs, the background
-page collected every completed navigation with the "http" or "https" schemes
-(using an UrlFilter for the listener of the webNavigation events)
-
-When the user clicks the browser action button, the popup is shown, and
-the stats saved using the storage API are retrived and rendered in the
-popup window.
-
-## What it shows ##
-
-* use the webNavigation API to monitor browsing navigation events
-* use an UrlFilter to only receive the webNavigation event using
-  one of the supported criteria.
-* use the storage API to persist data over browser reboots and to share it
-  between different extension pages.

-# notify-link-clicks-i18n
-
-**This add-on injects JavaScript into web pages. The `addons.mozilla.org` domain disallows this operation, so this add-on will not work properly when it's run on pages in the `addons.mozilla.org` domain.**
-
-## What it does
-
-This extension includes:
-
-* a content script, "content-script.js", that is injected into all pages
-* a background script, "background-script.js"
-
-The content script listens for clicks in the page it's attached to.
-If a click is on a link, the content script sends the link's href
-to the background script.
-
-The background script listens for this message. When the background script
-receives the message, it displays a notification containing the href.
-
-The notification's content, as well as the extension's name and description, are
-localized into German, Dutch, and Japanese, as well as the default en-US.
-
-# What it shows
-
-* how to inject content scripts declaratively using manifest.json
-* how to send messages from a content script to a background script
-* how to display system notifications using the notifications API
-* how to use the internationalization (i18n) system

-# page-to-extension-messaging
-
-## What it does
-
-This extension includes a content script, which is injected only into: "https://mdn.github.io/webextensions-examples/content-script-page-script-messaging.html".
-
-The content script listens for clicks on a particular button on the page. When the button is clicked, the content script sends a message to any scripts running in the page.
-
-Conversely, the content script listens for messages from the same window posted using window.postMessage. When the content script receives such a message, it displays an alert.
-
-To test it out, visit https://mdn.github.io/webextensions-examples/content-script-page-script-messaging.html and press the buttons. One button sends a message from the page script to the content script, the other button sends a message in the other direction.
-
-## What it shows
-
-How to exchange messages between an extension's content scripts, and scripts running in a web page.

-# Quicknote
-A persistent note/to-do list application — click a button in your browser and record notes, which will persist even after browser restarts.
-
-Works in Firefox 47+, and will also work as a Chrome extension, out of the box.
-
-## What it does
-
-This extension includes:
-
-* A browser action that creates a popup — within the popup is:
-	* Two form elements for entering title and body text for a new note, along with a button to add a note, and a button to clear all notes.
-	* A list of the notes that have been added to the extension — each note includes a delete button to delete just that note. You can also click on the note title and body to edit them. In edit mode, each note includes:
-		* An update button to submit an update.
-		* A cancel button to cancel the update.
-		
-Quicknote uses the WebExtensions [Storage API](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/storage) to persist the notes.
-
-## What it shows
-
-* How to persist data in a WebExtension using the Storage API.

-# React / ES6 Popup Example
-
-## What it does
-
-This is an example of creating a browser action
-[popup](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Add_a_button_to_the_toolbar#Adding_a_popup)
-UI in [React][react] and [ES6](http://es6-features.org/) JavaScript.
-
-## What it shows
-
-* How to bundle [React][react] and any other [NodeJS][nodejs] module into an
-  extension.
-* How to transpile code that is not supported natively in
-  a browser such as
-  [import / export](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import)
-  syntax and [JSX](https://facebook.github.io/react/docs/jsx-in-depth.html).
-* How to continuously build code as you edit files.
-* How to customize [web-ext][web-ext] for your extension's specific needs.
-* How to structure your code in reusable ES6 modules.
-
-## Usage
-
-First, you need to change into the example subdirectory and install all
-[NodeJS][nodejs] dependencies with [npm](http://npmjs.com/) or
-[yarn](https://yarnpkg.com/):
-
-    npm install
-
-Start the continuous build process to transpile the code into something that
-can run in Firefox or Chrome:
-
-    npm run build
-
-This creates a WebExtension in the `extension` subdirectory.
-Any time you edit a file, it will be rebuilt automatically.
-
-In another shell window, run the extension in Firefox using a wrapper
-around [web-ext][web-ext]:
-
-    npm start
-
-Any time you edit a file, [web-ext][web-ext] will reload the extension
-in Firefox. To see the popup, click the watermelon icon from the browser bar.
-Here is what it looks like:

-
-## Icons

-The icon for this extension is provided by [icons8](https://icons8.com/).

-
-**This add-on injects JavaScript into web pages. The `addons.mozilla.org` domain disallows this operation, so this add-on will not work properly when it's run on pages in the `addons.mozilla.org` domain.**
-
-## What it does
-
-This extension includes:
-
-* a content script, "content-script.js", that is injected into all pages
-
-The content script listens for text selections in the page it's attached to and copies the text to the clipboard on mouse-up.
-
-## What it shows
-
-* how to inject content scripts declaratively using manifest.json
-* how to write to the [clipboard](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Interact_with_the_clipboard)
-
-## Note
-* If the `copySelection` function was in a browser event `clipboardWrite` permissions would be required e.g.
-```
-"permissions": ["clipboardWrite"]
-```
-See [Interact with the clipboard](https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Interact_with_the_clipboard.)

-# user-agent-rewriter
-
-## What it does
-
-This extension uses the webRequest API to rewrite the browser's User Agent header, but only when visiting pages under "https://httpbin.org", for example: https://httpbin.org/user-agent
-
-It adds a browser action. The browser action has a popup that lets the user choose one of three browsers: Firefox 41, Chrome 41, and IE 11. When the user chooses a browser, the extension then rewrites the User Agent header so the real browser identifies itself as the chosen browser on the site https://httpbin.org/.
-
-## What it shows
-
-* how to intercept and modify HTTP requests
-* how to write a browser action with a popup
-* how to give the popup style and behavior using CSS and JS
-* how to send a message from a popup script to a background script

-# WebExtension Webpack Example
-A minimal example of how to use [webpack](https://webpack.github.io) to package
-[npm](https://npmjs.com) modules so they can be used in a WebExtension.
-The example package used by this extension is `left-pad`, an essential package
-in almost any situation.
-
-## What it does
-This example shows how to use a node module in a background and a content script.
-It defines two build targets in [webpack.config.js](webpack.config.js), they each
-generate a file that includes all modules used the entry point and store it in
-the [addon](addon/) folder. The first one starts with [background_scripts/background.js](background_scripts/background.js)
-and stores it in `addon/background_scripts/index.js`. The other one does the
-same for [popup/left-pad.js](popup/left-pad.js) and stores it in `addon/popup/index.js`.
-
-The extension includes a browser action with a popup, which provides an UI for
-running left-pad on a string with a chosen character. The operation can either be
-performed with the left-pad module included in the panel's script or in the
-background script.
-
-## What it could do
-This could be infinitely extended - injecting global jQuery, adding babel,
-react/jsx, css modules, image processing, local modules and so on.
-
-## What it shows
-
- - How to use npm or custom modules in a WebExtension.
-
-## How to build it
-
- - `npm install`
- - `npm run build`
-
-The WebExtension in the [addon](addon/) folder should now work.
-
-## What about Browserify?
-Browserify works just as well as webpack for extensions, in the end it's a
-personal choice about your prefered tool.
-
-## Live-development
-Additionally to watching the folder with your `manifest.json` in it, you will also
-have to run webpack in watch mode.
